ROBERT L. WARNER, 0F CONCORD, MASSACHUSETTS.

SIGHT FOR FIREARMS.

Application filed September 13, 1913.

To all whom it may concern:

Be it known that I, ROBERT L. IVARNER, of Concord, in the county of Middlesex and State of Massachusetts, have invented a new and useful Sight for Firearms, of which the following is a specification.

My invention relates to that class of sights for firearms in which a spring sight member is used and my invention consists partly in providing means to continuously raise or lower the sight and partly in providing a sight which is operative in any position whatever within its range of travel.

My invention further consists in other features hereinafter pointed out.

In the drawings: Figure 1 is an elevation of a sight embodying my invention in position on a firearm; Fig. 2 is a plan of the sight itself; Fig. 3 is an end elevation of the spring sight member; Fig. 4 is a section on line 44 of Fig. 2; Fig. 5 is a section on line 55 of Fig. 2; Fig. 6 is a section on line 6-6 of Fig. 2; Fig. 7 illustrates a modification of the holding mechanism; Fig. 8 illustrates another modification of the holding mechanism; Fig. 9 is an enlarged sectional detail of the modification of the fixed spring abutment; Fig. 10 is a section on line 1010 of Fig. 9; Fig. 11 is an end view of Fig. 9 looking in the direction of the arrow; and Fig. 12 is a modification of the spring mechanism for holding the rotary member; Fig. 13 is a central sectional detail of the portion N of Fig. 12.

The body A of the firearm has boss B to which is connected by dove-tailed connection and by the screw 6 base D to which is connected by screw (Z the spring member E having near one end sighting aperture 6 and having on its under side projection 6. Base D is made in one piece and comprises bearing portions 6 e for the rotary member hereinafter described and also comprises housing 6 for the plunger actuating mechanism hereinafter described.

The rotary member for changing the position of the spring sight is made in one piece and comprises knurled portion f, scaled portion f, cylindrical portion f having notches or depressions f and rotating in bearing portion 6 annular flanges f f cam portion 7 and stop F. The rotary member is inserted in base member D and the spring sight member E having been raised before such insertion is then lowered Specification of Letters Patent.

between the annular flanges f, f so that these flanges not only furnish guides for the up and down movement of the spring sight member but the latter prevents axial movement of the rotary member and thereby prevents accidental removal of the latter.

Notches f are successively engaged by plunger 9 which is normally pressed toward the rotary member by spring 9 the fixed abutment of which is pin 9 having a head 5 which is in screw threaded engagement with the interior or housing 0*. Fixed mark is for use in cooperation with the scale on the scaled portion f, it being clear that any desired scale may be used depending upon the fineness of adjustment desired.

The cam surface 7 is continuous and progressively and gradually changes in its distance from the axis of the rotary member so that rotation in the direction of the arrow in Fig. 5 will continuously, gradually and progressively adjust the spring sight member in any position whatever within the range of travel of the rotary member, this range being limited by stop f one side of which engages projection e to limit the movement of the rotary member in one direction and the other side of which engages said projection to limit the movement of the rotary member in the other direction.

In Fig. 7 I show the rotary member having cylindrical portion is engaged by pin is. This form may be preferable for some purposes as the rotary member may be adjusted and held in any position whatever within its range of travel, this form lacking the notches f of Fig. at but being otherwise substantially the same as the form of Fig. 4.

In Fig. 8 I show another modification which is much like the form of Fig. 4 except that the cylindrical portion 1 is knurled and engaged by pointed pin 1', this form providing that the rotary member may be adjusted and held in any position whatever within its range of travel.

In Figs. 9, 10 and 11 I show on a larger scale a modification of the fixed abutment for the spring. In this form the abutment M has two radial lugs m m which enter slots m m in the base D, abutment M being slid horizontally into the housing 6 until the lugs m m are opposite the curved slots m m when member M is turned a quarter turn and its lugs then bear against the portions m m so that member M can not be acciw i UZWHE dentally removed. In this form no screw threading of the abutment or of the housing is required.

In Figs. 12 and 13 I show a modification in which the cylindrical portion N of the rotary member has a groove 41. with notches n, the pin a being adapted to successively engage the notches and normally lying in said groove so that it prevents axial movement of the rotary member. The Wall of the groove toward the spring member is beveled at a so as to reduce the friction on pin of. The groove a does not extend all the way around the surface of portion N but there is in the plane of the groove a portion a which will engage pin a and thereby limit the rotary movement of the rotary member so that the pin a not only engages the notches but prevents axial movement of the rotary member and also limits the rotary movement of the rotary member. Although this function of pin a preventing axial movement is new with me I do not claim it broadly in this application because broadly it is probably an invention distinct from the continuous elevation feature.

It will be observed that my invention provides gradual and continuous adjustability and that the rotary member may be held in any position Whatever within its range of travel, the notches in some of the forms shown providing special holding means at particular points although in these forms the rotary member will be effectively held in any position whatever that may be desired by the user.

It will be further noted that my sight is more easily operated than heretofore, particularly on account of the continuous adjustability due to the cam surface in the form of sight shown.

It will be clear moreover that my invention is much more compact and simple than any heretofore made.

What I claim is:

1. A sight for firearms comprising a cam mounted to rotate on an axis crosswise of the firearm, said cam having a continuous surface on its exterlor the distance of which from said axis gradually changes circumferentially, a spring sight member fixed at one end and having its other end movable and having a wide face bearing directly on the cam, and means to hold the cam with any desired portion of its acting surface supporting the spring.

2. A sight for firearms comprising a spring sight member; and a rotary member to change the elevation of said sight member said rotary member having two annular flanges to guide the movement of the sight member.

3. A sight for firearms comprising a spring sight member; a rotary member to change the elevation of the sight member; a spring-actuated plunger acting to hold said rotary member in the desired position; and a base made in a single piece and comprising a bearing for said rotary member and a housing for the plunger-actuating mechanism.

4. A sight for firearms comprising a spring sight member having one end fixed and the other end movable and having a projection on its lower side; a rotary member having a continuous surface to engage said projection to change the elevation ofv said sight member and having a stop to engage said projection to limit the rotation of the rotary member.
